Sets are a powerful and commonly used tool in production pipelines, but they are not without their dangers. In this post we look at the details of how they work, and share some tips for avoiding their pitfalls.Continue reading “Let’s talk about sets”
Execute the following via the PythonEditor :
import GafferScene n = GafferScene.ShaderAssignment() n["in"]["childNames"].setValue( IECore.InternedStringVectorData( [ "turtles", "all", "the", "way", "down" ] ) ) root.addChild( n )
Then look at the innocent looking ShaderAssignment node in the HierarchyView, and marvel at its recursive uselessness.
How does this work? Answers on the back of a postcard please…
Let’s face it, there’s only so much you can learn about Gaffer from a ball of cows. Wouldn’t it be great if there were some more comprehensive examples that resembled how you might work in a studio environment? Something with real assets and light rigs, that showed how to build a multi-shot workflow using a single template script? Well, now there is!Continue reading “New Gaffer Examples”
Gaffer allows scene locations to be organised into sets, and then uses a simple expression language to combine sets for use in light linking, shader assignments and the like. In this short post we’ll discuss a historical limitation of set expressions and present some useful improvements made in Gaffer 0.56.0.0.Continue reading “0.56.0: New set expression operators”
A common pattern that arises in production is the “shot-specific branch switcher”, typically using a Switch or NameSwitch node to choose the right branch for the current shot. In the fictitious example below, this pattern is employed to select the right render settings per shot, with an ArnoldOptions and StandardOptions node on each branch.Continue reading “What’s cooking? : Spreadsheet node”
Another major release, so soon? You bet. This time we have fewer changes, but they’re quite far-reaching. Included are major updates to the main application’s editor UI, new scene manipulator features, and the new CopyPrimitiveVariables and NameSwitch nodes. Let’s take a tour.Continue reading “Gaffer 0.55.0.0”
